     76Configuration:  [[BR]]
     77 * Only support for VMs;   largest to date 20 nodes;  to date, all on one aggregate
     78 * One extra VM  for "Global Node"
     79 * Add desired measurements to request rspec
     80 * Compatible image for quick setup

    84 Any topics, suggestions and issues suggested by members of roundtable?

     961)  Issues:
     97 * images
     98 * rspecs, since slight differences between ExoGENI and InstaGENI
     99 * workflow differences
     100
     1012)  Helpful:
     102 * list of reference experiments
     103 * repository of rspecs
     104
     1053)  Start testing soon!

     130Post-boot scripts can do anything a shell script can do
     131
     132Prime use:  connect OMF RC on node into messaging system, so that OMF EC can talk to node

    125152 * move towards instrumentize script, driven by rspec ext
    126153
    127 Or is there a better solution?  [[BR]]

    134  * List of issues
    135  * Team to continue discussion
     154Conclusions:
     155
     1561)  Can do equivalent of post-boot script in InstaGENI
     157
     1582)  Instrumentize script uses ssh, checks config, then sets config
     159
     1603)  Would like to be able to easily setup a basic set of measurements
     161
     1624)  Not clear how to resolve;  next:
     163 * draw out both flows
     164 * discuss
     165 * try to unify
     166
